Definitions

  • This carrier section is advantageously of frustoconical or frustopyramidal design or constructed with a plurality of axially successive step sections.
  • perforated-disk carrier makes it possible to use perforated disks with comparatively small dimensions, advantageously making it possible to save on material for the perforated disks.
  • a particular advantage is also provided by the fact that the perforated disk to be installed is not connected rigidly either to the valve seat body or to the perforated-disk carrier, thus completely avoiding distortion of the perforated disk due to welding or other disadvantages resulting from conventional joining methods.
  • FIG. 1 shows an injection valve illustrated in part, according to the present invention.
  • FIG. 2 shows a perforated-disk carrier with a tapered carrier section, according to the present invention.
  • FIG. 5 shows perforated disks for the perforated-disk carrier shown in FIG. 3.
  • FIG. 1 illustrates, as an exemplary embodiment, part of a valve in the form of an injection valve for fuel injection systems of mixture-compressing applied-ignition internal combustion engines.
  • the injection valve has a tubular valve-seat carrier 1 in which a longitudinal opening 3 is formed concentrically with a valve Longitudinal axis 2.
  • a valve needle 5 Arranged in the longitudinal opening 3 is a valve needle 5, which is, for example, tubular and, at its downstream end 6, is connected to a valve closing element 7, which is, for example, spherical and on the circumference of which there are, for example, five flats 8.
  • the flats 8 on the valve-closing element 7 allow fuel to flow in the direction of a valve seat surface 9.
  • the carrier section 25 is designed with four steps 37, the following gradation seems suitable, for example: 0.1 mm; 0.15 mm; 0.2 mm; 0.25 mm, these figures in each case being intended to indicate the axial distance of each step 37 from the end 17 of the valve seat body 16.
  • the four steps 37 it is thus possible to insert four different sizes of perforated disk 26 in the carrier section 25, which, respite the steps 37, is still basically dish-shaped.
  • a through opening 36 is again provided in the bottom section 35 of the carrier section 25.
  • FIG. 6 shows a perforated-disk carrier 21 in plan view, this carrier differing from those previously shown in that quadrilateral and, in particular, also square perforated disks 26 can be inserted into it.
  • the quadrilateral carrier section 25 Due to the quadrilateral carrier section 25, the annular section 19 is now no longer of circular design but is distinguished on the outside by a circular boundary and on the inside by a quadrilateral boundary. However, it performs the same functions as before since the fact that it rests against the end 17 of the valve seat body 16 allows the leaktight weld 23 to be applied in a ring.
